Hi guys n gals I've got a 2.0Tdci 2007 focus. Getting it remapped on Saturday to push it to 170bhp 385Nm. I was thinking of up rating my turbo also and get a hybrid...is this a good idea or not? Opinions please

In my opinion, i would not bother with a hybrid turbo, and stick with the stock one, on your car

you could upgrade the exhaust with a cat/ DPF delete, and a 2-1/2" system - it would be simpler easier to do and is more likely to get improved results (almost definately better results)

the turbine housing is part of the exhaust maniflold, so there is no easy way of changing the turbine,(unless you have a custom manifold fabricated- ££££s/ serious modding) this leaves the compessor -

if the compressor is upgraded without the turbine, it can produce a mismatch, often, a massive compressor wheel and housing is added, this has to be driven by the small turbine, the extra mass of the wheel means it takes longer to spin up, if you are lucky the extra gas flow compensates for this, and it produces similar results as the stock compressor, if yiu are unlocky the additional lag (or raised boost threshold) puts a big "hole" in the power/ toruue curve

That might be ok if it raises the top-end power, but a regular diesel revs so low that you are liable to just cut some of the bottom-end - so hybrid turbos are often best left to high-revving petrol engined cars and very heavily modified , high revving diesels

the turbine really has to be matched to the car, with careful selction one could be chosen for just a little bit more gas-flow at the top-end (without adding too much lag at the bottom) - but then you are talking a realatively small improvement for a considerable cost - as progressively bigger compressors are chosen the lag increases

so it can end up being a lot of hassle/ money spent with little improvement, or a lot of lag/ loss of bottom end power

Im not saying, with the correctly selected turbine, and fitted/ set up by experts it could not be really exellent, but for most people sticking with the stock turbo is the best way to go - especially as you may find to get the best out of it yiou start needing injector, clutch/ trans (the DMF would probably have to go too) - i had to get a carbon-fiber/ kevlar heavy-duty clutch SMF to handle the extra torque - you might find you get "carried away" with the project - check out my build thread in my profile

After having advised you not to go for the hybrid- i would love to see a balls-out (proper fast) mk2 Focus 2.0TDCI ST replica , or a sleeper

Thanks for that mate money is certainly not something I can be throwing away so after remap will just look at removing dpf...happy days
